FOSTA Posted October 23, 2012 Share Posted October 23, 2012 (edited) As some of you will know, there isn't any company's that sell cams for the 2jz-GE engine (apart from the 2jz-GE vvti) This is due to the exhaust cam having a gear on it for the distributor. Now I've found a company that can make our existing cams to any spec we want as for me I want my cams to be 264 on both inlet and exhaust. They do this by hard welding them and then grind them down to the spec we require. I've contacted the company and asked if they would be willing to do discount on a group buy and they have agreed! So this is just to see if there is any interest from our fellow NA-Ters. The price they have quoted for one set is $400-$450 ( so thats between £249-£280 uk currency ) depending on spec but that's just for one set witch i will be buying regardless! But I asked if they would be willing to discount on a group buy and they have agreed. I can't see there being much interest as I don't think there is many people NA-T over here but I just thought I would let the ones who are know. Put your names down if your interested! (this is not a commitment! This is just to get an idea of how many people are interested in a set, and once we get the discounted price back you can then decide if you want to go ahead and purchase). 1.FOSTA Edited October 24, 2012 by FOSTA (see edit history) Quote Link to comment Share on other sites More sharing options...

There are these ones, they are more expensive though http://www.ttcperformanceproducts.com/ttc-performance-2jzge-268-2268.html Quote Link to comment Share on other sites More sharing options...
Noz Posted October 23, 2012 Share Posted October 23, 2012 TTC been doing this for years. They can do up to 316 duration cams. Quoted me $800 for a set previously (any duration/lift). I'll put my name down, just to get interest, price depending obviously. 1. FOSTA 2. Noz Quote Link to comment Share on other sites More sharing options...

At the top it has a box that asks the customer to supply cores (cams) or they will sell you there's for an extra $300. So it looks like they are doing the exact same thing and hard welding the existing cams so they are still not an aftermarket cam, they are just the factory cams hard welded. So the same as what people will be getting here but at less than half the cost. Thanks for that mate, I didn't know someone else was doing this also Quote Link to comment Share on other sites More sharing options...

Noz Posted October 24, 2012 Share Posted October 24, 2012 Also found this for OEM cam duration spec: 2JZ-GE (without VVT-i) Displacement: 2997cc Intake camshaft duration: 233 Exhaust camshaft duration: 236 Valve overlap: 6 degrees Intake valve lift: 8.26 mm Exhaust valve lift: 8.41 mm Intake valve diameter: 33.5 mm Exhaust valve diameter: 29.0 mm Intake valve overall length: 98.55 mm Exhaust valve overall length: 98.55 mm Valve stem diameter: 6 mm Valve spring Free length: Installed height: Valve lifter bucket Diameter: 30.96 mm - 30.98 mm Bore diameter: 30.99 mm - 31.02 mm While the 2JZGE has a 45 degree included valve angle versus the 22.5 degrees of the 3VZ/1MZ, it does not considerably outperform the 3VZ/1MZ even with slightly hotter cams and increased valve lift. In fact, if the engines were equal in camshaft duration, valve lift, and valve diameter, there's a good chance that either "economy" motor would outperform the "performance" oriented motor, if only slightly.

FOSTA Posted October 28, 2012 Author Share Posted October 28, 2012 Oooo very good! Where both cams the same? Ie: inlet 268 and exhaust 268? Quote Link to comment Share on other sites More sharing options...
tkddav3 Posted October 28, 2012 Share Posted October 28, 2012 could you not just install coil packs thus deleting the need for the dizzy gear allowing you to run "of the shelf" cams? or did i just speak a load of crap that means nothing and should go sit in the corner with mr bailey?

Noz Posted October 28, 2012 Share Posted October 28, 2012 installing coils isn't the issue. its changing the ignition system so the ecu can fire each cylinder with the coils, a dizzy means you only need one output. with no dizzy your need a standalone ecu and another sensor to control the firing order. or use coils with the cam position sensor, but that only means better ignition still need cam gear. modifying cam's is a look less hassle than changing ignition system (though possibly not as cheap if your going standalone anyways) Quote Link to comment Share on other sites More sharing options...
Herb Posted October 28, 2012 Share Posted October 28, 2012 Sounds pretty interesting! would it also be possible to get some slightly hotter cams to run on the GE in its naturally aspirated form? (to run on stock ECU!?) regards, Herbert Quote Link to comment Share on other sites More sharing options...

Noz Posted October 29, 2012 Share Posted October 29, 2012 Yes. But you wouldn't be able to have much higher duration or see much difference. Bang for buck, it would cost more than it's worth still being NA I expect. Quote Link to comment Share on other sites More sharing options...
